There are four main sequelae after high-voltage electric shock: 1. Cardiovascular system. Manifestations include worsening coronary thrombosis and post-infarction sequelae, pain in the precordial region, and arrhythmias, cardiac insufficiency, impaired renal function, or thrombosis.2. Central nervous system. Peripheral neuropathy, lateral sclerosis, paralysis, cortical atrophy, secondary epilepsy. Among the sensory neurologic sequelae can be problems with vision; occipital infarcts can cause ipsilateral hemianopsia, optic nerve atrophy, electroshock cataracts, reduced visual accuracy, aggravation of retinal detachment, retinal damage, or auditory problems due to trauma to the tympanic membrane and damage to the inner ear in the case of concomitant deafness and dizziness.3. Functional sequelae. From flexural folds, abnormal scarring, damage to tendon cords, or even contractures from amputation.4. Psychological sequelae. Symptoms are more varied, approximating the subjective symptoms of cranial trauma, negativity, insomnia, and personality instability. Severe hypoxia caused by electric shock injury is also more common, general oxygen therapy is not effective, then you can use hyperbaric oxygen therapy to improve the oxygen content. For patients with clear consciousness, fatigue, panic, generalized weakness, generally bed rest for a few days can be recovered, and symptomatic supportive treatment if necessary.
